Included features

FreshWater® Salt System

Every Utopia Series spa features the intuitive FreshWater® Salt System, which generates chlorine from salt to keep water clean and fresh up to three times longer than standard systems.

FiberCor® Insulation

All Caldera Spas use FiberCor®—a high-density insulation applied at 2 lb. per cubic foot, making it four times denser than standard ½ lb. urethane foam for superior heat retention.

Comfortable, Ergonomic Seating

Ergonomically sculpted seats cradle your body, support proper alignment, and help decompress your spine. Combined with the water’s natural buoyancy, they ease pressure on areas stressed throughout the day.

Hot Tub Circuit Therapy

Each seat in a Caldera spa targets a specific muscle group—from neck and shoulders to back, hamstrings, calves, and feet—delivering a focused, full-body massage as you move from seat to seat
